BROCKTON – Video surveillance from a Brockton gas station shows a man striking Jacinto Vieira twice with what police believe to be a knife, Plymouth County Assistant District Attorney Russ Eonas said in court Monday.

Terrance Terrell Richardson, 19, of 129 Frankton Ave., Brockton was arraigned on Monday after he was charged with murder and armed robbery in the stabbing death of Vieira, 19, Friday. Vieira was found on the porch of 56 Green St.

Richardson was ordered held without bail until a probable cause hearing in May.

A woman found Vieira on the steps of her Green Street porch as she was leaving for work on Friday, April 11. He was conscious and barely breathing, and died shortly after he was brought to the hospital, Eonas told the court.

Investigators followed a trail of blood from the doorstep where Vieira was found to the Yasso Stop ‘N Gas at the corner of Warren Avenue and Green Street, about 500 feet away.

Eonas said surveillance footage from the gas station showed three men, one of which was Richardson, about 3:40 a.m. standing in the parking lot.

“A little while later a fourth individual, later identified as the deceased in this case as Jacinto Vieira, walks down the street,” Eonas said. “Based on his (Vieira’s) mannerisms you can see that there is some sort of dialogue between the three individuals as well as Mr. Vieira. It appears to be a disagreement by his hand gestures and the like.”

Eonas said at one point Richardson, whom “potentially” had a knife in his hand, struck Vieira twice “in rapid succession one after another, once in the chest area and once toward the facial area.”

About a minute later the three men were then seen heading in the direction of Green Street, where Vieira had gone, he said.

One of the men, Antoine Richardson, Terrence Richardson’s cousin, admitted to police that he took his wallet, cell phone and some personal items, Eonas said.

Antoine Richardson was charged with armed robbery in the incident.

Police spoke to a person, who was not named in court, “who indicated that Terrence Richardson had contacted him the next day and said he needed to get out of town or lay low for the next couple of days outside of Brockton.”

Terrence Richardson’s attorney, David Sorrenti, who practices out of Brockton, said his client graduated from Brockton High School in 2013.

Sorrenti said Vieira was stabbed eight times, although prosecutors said Terrence Richardson is shown on camera stabbing Vieira twice.

He said “there are six stab wounds unaccounted for” and there was nothing to indicate which of the stab wounds proved fatal for Vieira.

“I think this case cries out for further investigation,” Sorrenti said.

Terrence Richardson will be due back in court for a probable cause hearing May 9.

Antoine Richardson was also arraigned Monday on the armed robbery charges and ordered held on $500,000 bail. He will be due in court May 9.
